To all wil/077e it' may concern:

Be it known that I, NEWTON C. SPRAGUE, l and the perforations thereininto the space of Minneapolis, Hennepin county, Minnesota, haveinventedcertain new and useful Improvements in Broeders, of which the fol- Theobject of'iny invention is to provide a broeder which is capable ofbeing taken apart readily forcleansing purposes or repairs.

A further object is to provide a broeder in which it willl beiinpossiblefor the chicken to come in direct contact with a heated surface. Afurther Objectis toprovide a broeder in which the circulation oit' purewarm air through the hover is positively insured.

Otherobjects of the invention will appearfrom the following detaileddescription.

l The invention consists generally in various constructions andcombinations, as is hercinafter described, and particularly pointed Aoutin the claims.

In the accompanying drawings, forming part of this specication, Figure 1is a perspective view of a brooder embodying my invention. Fig. 2 is atransverse `vertical sectional view oi the same.

In the drawing, 2 represents the walls'o'f the broeder supported uponsuitable legs 3 and having areinovable covei 4.

o is the bottom of the broeder, having a central'opening 6, over which adrum 7, pref- 'erablycylindrical in form, is removably. arl ranged on aiiange 6.

The Walls of' this'drum 'at the top have a series of holes 7 and the.top of the drum 7 has avcap or dome 8,on

which a circularplate 9, forming the top of the hover, is centrallyresting upon. clips ,10, provided on the top of the drum. .The plate 9has suitable exhaust-holes 11, communicating with the interior of thebrooder, and -a iiexible curtain 12 is suspended from the-said plate anddepends to a point near the floor of the brooder and is provided withaseries ofV slits 13 to facilitate the passage of the chickens from thebroeder-chamber to the space within the hover. The cover 4 is providedWith suitable exhaust-openings 14, through which the foul air isdischarged. `1

Beneath the `flooris a plate 15, and between said plate and floor areflues 16, communicating with the interior of the drum 7 and with theopen air through ports 17 in said plate. The cool air entering the ports1.7 flows up around and through the drum inclosed bythe liover-curtain.A flange 18 is mounted on the plate and vsupports an iniperforate drum19, which projects lup into the drum -7 and is spaced i'roin the wallsthereof` rlhe drum 19 is accessible after the drum 7 is removed and mayalso be detached for convenience in cleaning. A pipe 2() is carried bythe plate 15 and extends up into the drum 19 and has anopen upper endcominunicating with the interior oi' said drum and an open lower end,into which the heating-lamp 21 is inserted. This lamp is mounted on asuitable track orl guide 22 and is adapted to be slipped in under thepipe 20, being limited in its movement by a stop 23,. so that noaccurate adjustment of thelamp x is required/it being merely necessaryto push it on the track as tar as 'it will go.

The lower end of the pipe has a cut-out portion 24 to permit the passageofthe lamp.

A ilue communicates with the space inclosed by the lamp 18 and the drum19 and leads out between the plate. 15 and the Iioor of the brooder tothe open air. The heat oi the lamp will create a circulation through thepipe 2() and the druin 19 and out through the ers-and as` the outer drumcannot become .hot it will be impossible for the chickens to be injuredthrough contact with a hot radiatingsurface. The circulation of airbetween the drums can be regulated so that the desired temperature canbe obtained inthe broeder and a perfect system of heating andventilatin'gsecuredyl Whenever desired, the cover of the broeder Ina beremoved, the hover-plate 9 lifted, an convenient access had to the drumsfor r oo the purpose of cleaning off the soot which will accumulatethereon. l

I claim as my inventionn 1 In a broeder, the combination, with a casinghaving a floor provided with an opening therein, of a perforate drummounted on said floor over said opening and spaced from the top of thebroc er, a'lhover-plate supported above said'drum and spaced from thetop and side Walls of the broeder, a curtain supported on saidhover-plate and inclosing sai drum, an imperforate drum arranged withinthe opening in said floor and spaced from the Walls and top of -saidfirst-named ,drum and having an exhaust or foul-air flue,

'means supporting said imperforate "drum,

facilitate the' cleaning of their interior surfaces, substantially asdescribed.

.2. In a-brooder, thr combination, with a :casin having a floor `rovidedwithan openn inggt erein anda ange surrounding the persame,"of a drumhaving a closed top an forate side Walls and an open bottom fittin oversaid ange, a hoven late supporte above said drum and s ace from the topof the brooder and the sidewalls thereof and having a curtain inclosingsaid'drum, av late arranged beneath the iioor' of the broo er, a

"secondfiange mounted on said plate beneath the, opening in said iloor,an imperforate air inlet and said imperforate drum having a` drumfitting 'on said second flange and eX- tending u through the opening insaid iior` into said' st-named drum and spacedtherefrom, and saidperforatedrum having a coldfoul-air exhaust, a pi eprojecting up throughsaid plate into said ipmperforate drum and a lamp arranged beneath saidpipe and said drums being removably mounted on said 'u' y pipe. .f

4. The combination, with a 'brooder-'cas-j 'ing having a floor providedwith an? opening projectin i iianges, whereby access may be had to theirinterior surfaces for cleaning purposes.

3. In a brooder,l the combination, With a casing having a 'floorprovided with an opening therein and a flange inclosing said open- Ying, of a perforate drum removably mountedon said ange, a plate arrangedbeneath said licor, a second flange/thereonl beneath the opening in saidiioor, an imperforate drum removably mounted on said second flangeA vandprojecting up through said opening into said perforate drum and spacedfrom the Walls thereof, said perforate drum having acold-airintake`opening, and said imperio- `rate drum having afoul-air-exhaust iiuefa pipe projectin up into said imperforate drum,and a Ia mp arranged beneath said'v therein, of a p'erforatedrum'ai'ranged over lsaid opening, clips `provided on the top'of vsaiddrum, a hover-plate resting upon said clips and spaced from thetop ofthe broeder and-'having eX-h'austopenings and 'a curtain .inclosing saiddrum, an imperforate drum up into said first-named -drum v through t ehole in said il-oor, means supporting said imperforate drum, a plateWhereon `said imperforate drum is supported, said erforate drum having acoldairintake ue,

`and said imp'erforate drum having an eX- haust-iiuefapipe supported insaid plate and r projecting' up into "said, imperfoate drum,

and a lamp 'arranged-beneath said pipe.

In Witness whereof I have hereunto `set my y hand this 19th day ofJanuary, 1906.,
